lykanbio.com website review

6 files are served with short cache lifetimes, so returning visitors download them again (420 KiB).

9 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.8 s.

About 144 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.1 s faster on a phone.

Your mobile performance score is 59 (desktop: 98). Pages that score under 90 lose visitors before the first paint.

7 images could be 394 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 550 ms faster on a phone.

About 90 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 600 ms faster on a phone.

Hubspot costs a phone 95 ms of main-thread work and 399 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

4 third-party services load with your homepage (Cookiebot, Hubspot and Cloudflare and others), adding 492 KiB and 303 ms of main-thread time.

3 long tasks block the main thread while loading, the longest for 74 ms. During a long task the page ignores taps.

Desktop scores 98 but mobile only 59. A gap that wide usually means heavy scripts and images that hit phones hardest.

Polyfills for old browsers add 10 KiB JavaScript that modern phones do not need.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Your largest element takes 9.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

The first text or image appears after 4.8 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 7.2 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 9.3 s. Good is under 3.8 s.

Real visitors wait 924 ms for your server to start answering (75th percentile). Good is under 800 ms.

Your homepage downloads 4.0 MB in 57 requests on a phone: media 2.5 MB (1), scripts 728 KiB (23) and images 635 KiB (21). Under 2 MB keeps phones on slow connections fast.

1 image (56 KiB) is JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

By the Sustainable Web Design model, a visit to your homepage emits about 1.14 g of CO₂e: 136.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 element use ARIA attributes their role does not allow, which confuses screen readers.

Certain ARIA roles must contain particular children: 1 element on the page fails this check, rated critical by axe-core.

1 button has no accessible name, so screen readers announce just “button”.

1 dropdown has no label.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

5 visible links have no text or label, so screen readers cannot say where they go.

1 form field has no label, so screen readers announce an empty box and autofill guesses.

5 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

The homepage links to 100 pages on lykanbio.com and 5 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

There is no https://www.roslinct.com/llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

https://www.roslinct.com/category/news is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

https://www.roslinct.com/cell-therapy-process-analytical-development, https://www.roslinct.com/cell-therapy-manufacturing-science-technology, https://www.roslinct.com/cell-therapy-clinical-commercial-manufacturing and https://www.roslinct.com/cell-therapy-quality-regulatory-compliance all use the title “Cell Therapy Analytical Development | RoslinCT”, and 1 other title repeat too. Search engines can't tell which page to show for a search, so each competes with the others.

https://www.roslinct.com/category/news has no meta description, so Google writes the search snippet from whatever text it finds.

https://www.roslinct.com/cell-therapy-process-analytical-development, https://www.roslinct.com/cell-therapy-manufacturing-science-technology, https://www.roslinct.com/cell-therapy-clinical-commercial-manufacturing and https://www.roslinct.com/cell-therapy-quality-regulatory-compliance use the same meta description. A description written for each page earns more clicks.

We fetched 15 pages linked from your homepage (of 34 found) and read each the way a search engine does.

9 of 39 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 520 words of visible text.

Loading the homepage contacts 8 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
